【WebService开发】之使用CXF开发WebService
1.开发服务端
a) 下载CXF：apache-cxf-3.1.6
b) 把cxf的jar包加入到项目中，其它不需要改变（同JDK开发webservice一样），webservice服务端开发完成。
2.开发客户端
a) 加入环境变量path中，E:\apache-cxf-3.1.6\bin
b) 在cmd命令下生成客户代码，命令为：wsdl2java url，该命令为cxf的bin目录下的功能。
c) 编写客户端测试代码
public class ClientTest {
public static void main(String[] args) {
HelloWSImplService factory = new HelloWSImplService();
HelloWs helloWs = factory.getHelloWSImplPort();
String result = helloWs.sayHello("xdy");
System.out.println(result);
}
}WebService请求的流程
一次web service请求的本质：
1.客户端向服务端发送了一个soap消息（http请求+xml片断）。
2.服务器端处理完请求后，向客户端返回一个soap消息。

CXF框架的使用
1、CXF的拦截器
为什么设计拦截器？
为了在webservice请求过程中，能动态操作请求和响应数据，CXF设计了拦截器。
拦截器分类：
1.按所处的位置分：服务器端拦截器，客户端拦截器。
2.按消息的方向分：入拦截器，出拦截器。
3.按定义者分：系统拦截器，自定义拦截器。
【示例】演示为客户端及服务端加入日志拦截器。
为服务端ServerTest加入日志拦截器。
public class ServerTest {
public static void main(String[] args) {
String address = "http://192.168.0.102:8989/day01_ws/hellows";
Endpoint endpoint = Endpoint.publish(address, new HelloWSImpl());
System.out.println(endpoint);
EndpointImpl endpointImpl = (EndpointImpl)endpoint;
//服务端的日志入拦截器
List> inInterceptors = endpointImpl.getInInterceptors();
inInterceptors.add(new LoggingInInterceptor());
//服务端的日志出拦截器
List> outInterceptors = endpointImpl.getOutInterceptors();
outInterceptors.add(new LoggingOutInterceptor());
System.out.println("发布webservice成功！");
}
} 为客户端ClientTest加入日志拦截器。
public class ClientTest {
public static void main(String[] args) {
HelloWSImplService factory = new HelloWSImplService();
HelloWs helloWs = factory.getHelloWSImplPort();
//发送请求的客户端对象
Client client = ClientProxy.getClient(helloWs);
//客户端的日志出拦截器
List> outInterceptors = client.getOutInterceptors();
outInterceptors.add(new LoggingOutInterceptor());
//客户端的日志入拦截器
List> inInterceptors = client.getInInterceptors();
inInterceptors.add(new LoggingInInterceptor());
String result = helloWs.sayHello("xdy");
System.out.println(result);
}
} 2、CXF自定义拦截器
AbstractPhaseInterceptor：抽象过程拦截器，一般自定义的拦截器都会继承于它
功能：通过自定义拦截器实现用户名和密码的检查
1.客户端拦截器：设置out拦截器，向soap消息中添加用户名和密码数据
public class MyInterceptor extends AbstractPhaseInterceptor {
private String name;
private String password;
public MyInterceptor(String name,String password) {
super(Phase.PRE_PROTOCOL);
this.name = name;
this.password = password;
}
/*
xiongdy
123456
xdy
*/
public void handleMessage(SoapMessage message) throws Fault {
List headers = message.getHeaders();
/*
xiongdy
123456
*/
//Document document = DOMHelper.createDocument();
Document document = DOMUtils.createDocument();
//
Element rootEle = document.createElement("xdy");
//xiongdy
Element nameEle = document.createElement("name");
nameEle.setTextContent(name);
rootEle.appendChild(nameEle);
//123456
Element passwordEle = document.createElement("password");
passwordEle.setTextContent(password);
rootEle.appendChild(passwordEle);
//添加为请求消息的
headers.add(new Header(new QName("xdy"), rootEle));
System.out.println("client-----handleMessage");
}
} 2.服务端拦截器：设置in拦截器，从soap消息中获取用户名和密码数据，如果不满足条件就不执行web service的方法
public class MyInterceptor extends AbstractPhaseInterceptor {
public MyInterceptor() {
super(Phase.PRE_PROTOCOL);
}
@Override
public void handleMessage(SoapMessage msg) throws Fault {
System.out.println("server-----handleMessage");
Header header = msg.getHeader(new QName("xdy"));
if(header==null) {
throw new Fault(new RuntimeException("用户名密码不存在 "));
} else {
Element data = (Element) header.getObject();
if(data==null) {
throw new Fault(new RuntimeException("用户名密码不存在22"));
} else {
String name = data.getElementsByTagName("name").item(0).getTextContent();
String password = data.getElementsByTagName("password").item(0).getTextContent();
if(!"xiongdy".equals(name) || !"123456".equals(password)) {
throw new Fault(new RuntimeException("用户名密码不正确"));
}
}
}
System.out.println("通过拦截器了！");
}
} 3.服务端测试代码：
public class ServerTest {
public static void main(String[] args) {
String address = "http://192.168.0.102:8989/day01_ws/hellows";
Endpoint endpoint = Endpoint.publish(address, new HelloWSImpl());
System.out.println(endpoint);
EndpointImpl endpointImpl = (EndpointImpl)endpoint;
//服务端的自定义入拦截器
List> inInterceptors = endpointImpl.getInInterceptors();
inInterceptors.add(new MyInterceptor());
System.out.println("发布webservice成功！");
}
} 4.客户端测试代码
public class ClientTest2 {
public static void main(String[] args) {
HelloWSImplService factory = new HelloWSImplService();
HelloWs helloWs = factory.getHelloWSImplPort();
//发送请求的客户端对象
Client client = ClientProxy.getClient(helloWs);
//客户端的自定义出拦截器
List> outInterceptors = client.getOutInterceptors();
outInterceptors.add(new MyInterceptor("xiongdy", "123456"));
String result = helloWs.sayHello("xdy");
System.out.println(result);
}
} /**********************************华丽分割线******************************************/
用CXF编写基于Spring的WebService
server端：
1. 新建web工程，导入cxf的jar包
2. 定义SEI和其实现
@WebService
public interface OrderService {
@WebMethod
public Order getOrderByNo(String orderNo);
}@WebService
public class OrderServiceImpl implements OrderService {
public OrderServiceImpl() {
System.out.println("OrderServiceImpl()");
}
public Order getOrderByNo(String orderNo) {
System.out.println("getOrderByNo() orderNO=" + orderNo);
return new Order(3, orderNo, 10000000);
}
}public class Order {
private int id;
private String orderNo;
private double price;
}3. 发布web service
beans.xml
Web.xml
index.jsp
contextConfigLocation
classpath:beans.xml
org.springframework.web.context.ContextLoaderListener
CXFServlet

client端
